PLEASE NOTE:

The main element is now defined in HTML 5.1


Notes

A Rationale / Use Case document for the addition of the main feature to HTML is available.

From publicly reported studies [1] of id values used in HTML content, the use of the strings "content" and "main" are common practice. A recent study has provided data which shows a strong correlation between the use of the aforementioned id values as targets for 'skip links' and also a strong correlation with the use of ARIA role=main on elements having the aforementioned id values.
